Are you installing calibre from the command line found at calibre - Download for Linux or are you using a repository or FlatPak version?

You are missing libglx read the first line of the error message you posted

I fixed the libGLX.s error but i now have these errors

qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: vnc, wayland-egl, offscreen, minimal, eglfs, wayland, linuxfb, vkkhrdisplay, minimalegl, xcb.

Aborted (core dumped)

Looking at the calibre Linux install page, there is a item under notes:

Quote:

If you get an error Could not load the Qt platform plugin xcb you are missing some needed X11-XCB libraries, such as libxcb-cursor0 or libxcb-xinerama0, for details see here.

Where here is is a link to a Mobileread thread: Calibre 5.0.1 Could not load the Qt platform plugin "xcb" FIXED
